Step‑by‑Step Instructions for Veggie-Packed Quinoa Casserole
Step 1: Cook the Quinoa
In a medium saucepan, bring 2 cups of vegetable broth to a rolling boil over high heat. Add 1 cup of rinsed quinoa, reduce the heat to low, cover, and simmer for 12–15 minutes, or until the liquid is absorbed. Once cooked, remove from heat and fluff the quinoa with a fork, allowing it to cool slightly as you prepare the vegetables.
Step 2: Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 1 small diced onion and 2 minced garlic cloves, sautéing for about 2 minutes until fragrant. Next, toss in 1 diced bell pepper, 1 diced zucchini, and 1 cup of sliced mushrooms, cooking for 5–7 minutes until they soften. Finally, stir in 1 cup of halved cherry tomatoes and 1 cup of chopped baby spinach, along with seasonings for a vibrant veggie mix.
Step 3: Prepare the Sauce
In a mixing bowl, combine 1 cup of tomato sauce with ½ cup of Greek yogurt and ½ teaspoon of red pepper flakes (if using). Mix thoroughly until creamy and smooth, allowing the sauce to become richly flavorful. Set this sauce aside to add to the Veggie-Packed Quinoa Casserole later.
Step 4: Assemble the Casserole
Preheat your oven to 190°C (375°F). In a large mixing bowl, combine the cooked quinoa, sautéed vegetable mixture, and prepared sauce. Stir until everything is well coated, then transfer the combined mixture into a greased 9×13 baking dish, spreading it evenly to form a solid base for the casserole.
Step 5: Add the Cheese Toppings
Sprinkle 1 cup of shredded mozzarella cheese evenly over the top of the filled baking dish. If desired, add ¼ cup of grated Parmesan cheese for extra flavor. Cover the dish with aluminum foil to keep the moisture in during baking, setting it up for a perfectly cheesy finish.
Step 6: Bake the Casserole
Carefully place the covered baking dish in the preheated oven and bake for 20 minutes. After this time, remove the foil to let the cheese brown, then bake uncovered for an additional 10 minutes. The casserole should be bubbly and golden when done—this is the perfect time to showcase its deliciousness!
Step 7: Let It Rest and Serve
Once baked, allow the Veggie-Packed Quinoa Casserole to rest for about 5 minutes before serving. This short cooling period helps settle the layers and makes it easier to slice and serve. Garnish with freshly chopped parsley or basil to elevate the presentation and add a pop of color!
